Figure 10From: Purification of DP 6 to 8 chitooligosaccharides by nanofiltration from the prepared chitooligosaccharides syrupMALDI-TOF mass spectrum of chitooligosaccharides. It showed the distribution of chitooligosaccharides. As expected, the final products were mainly composed of DP 6 to 8 chitooligosaccharides, which was similar with the HPLC results mentioned before.Back to article page
